' by declare the "following to be a full, clear,

Be it known that I, GEoRen MooBE, citizen of the United States, resldlngat J oplin, in the county of Jasper and-State of Missouri, haveinventedcertain new and usefulImprovements in Filters; and Ido hereand exactdescription of thelinvention, such as will enable others skilled in'theart to which it appertains tomake and use the same. 7

7 This invention relates'to improvements in filters and particularly tothe type adapted for the purification of liquids.

' The primary object in view is the provi-- sion of means forautomaticcleansing of filtering material in an effective manner and to remove theclogging matter from the filter so the flow'will notbe' stopped. 1 Withthis. and other objects in view,as

will inpart hereinafter bestated and in -part become apparent, the inentionjcomprises certain "novel '"cons'truction's,- combinations ofmodified embodiments. H V

A preferably annularcontainer 2 is connected to pipe 1, and is provided with an upstandingair dome or chamber 3, the dome being open only at its lower end andthreaded into or otherwise fixed to the container 2.1 An, annular, in-

wardly projecting shoulder 4 is formed in container 1, and a filterisclamped between.

said shoulder and the lower end of .dome or tube 3. Said filter consistsof a filter'fabric or sheet. 5.confinedand protected at each side bywire mesh 6. An upstanding'stay 7 is disposed centrally of container-.2to aid inpreventing sagging of the filter.

Apertures 9formed in disk 8 admit filtered water i to dome 3, and a spigot-or otherappropriate valve 10 controls discharge of filtered water 1 clinedlaterally as seen in Fig. 3, to throw its stream at one'sideof thechamber,--so as to produce a whirlingmovemeut of the contained water,and to .causethe water to wash the under. or approach surface of thefilter.
